The Crazy Whale Facts

Since the late 1960s, blue whales have lowered their sound. They've gone more baritone, shifting the equivalent of three white keys on a piano - which ironically used to once be made of whale bone. And it's really mad how they've completely changed as well the distance that they can communicate in. I read that whales, if there's predators around and they have their baby whales near them, they'll whisper like, guys, we've got to be, like, whales whisper. That's pretty fascinating that they know to lower their tone.
